I had mine for maybe 2 years before I took them out while pregnant. I planned on taking them out closer to birth and maybe putting them back in when I was done breastfeeding, but I was so uncomfy with them while pregnant and they were not healing. I kept snagging them, which was so painful, and I was so relieved they closed up tbh. I won’t be repiercing them.
I took mine off during pregnancy because they became really sensitive and overall uncomfortable, I do think my breastfeeding journey was easier without them, milk still comes out of the piercing holes
Honestly, my boobs got so huge the first couple months of pregnancy that my piercings hurt my nipples. I had mine for 6 years and I took them out while like 2 or 3 months pregnant. While pumping I can still see some milk coming through the previous piercing holes but I haven’t attempted to put the piercings back in. Just easier all around not having them anymore for me.
